Quantum information encoded in spinning black holes

Posted by in categories: computing, cosmology, quantum physics

Rotating black holes can implement quantum gates and quantum circuits, like Bell states, which are quantum counterparts of the classical computer programing.

The black holes sparked the public imagination for almost 100 years. Their presence in the universe has been debated for long; however, the detection of X-ray radiation coming from the center of the galaxies has put an end to the discussion and undoubtedly proven their existence.

The vast majority, if not all, of the known black holes were unveiled by detecting the X-ray radiation emitted by the stellar material around them. Black holes emit X-ray radiation, light with high energy, due to the extreme gravity in their vicinity. X-ray photons emitted near rotating black holes not only exposed the existence of these phantom-like astrophysical bodies, but also seem to carry hidden quantum messages.

A recent article posted in the pre-printed arXiv (“Photonic Bell states creation around rotating black holes”) argues that X-ray radiation coming from fast spinning black holes encompasses quantum information.
